The" opposite-end of the braces are secured to'the bars 1" in any well known manner,

Each member 2*" may be formed from a hollow section of material and be providedwith projecting'lugs 2 to I maintain the member 2 substantially concentric to the pipe 2*, to form a relatively small or thin medium circulating space en- Figure 1 is a perspective view of a heattirely around the member 2 The lug 2 .tional view, somewhat enlarged, parts of,

are preferably formed integral .with and uniformly spaced around a ring 2,'which fits the pipes 2 Any desired number of rings 2. may be placed on and spaced along each pipe 2*" to maintain it at'all points concentric to the adjacent pipe 2. 2 indicates suitable plugs or closing devices fitted -in a liquid tight manner to the opposite ends of each pipe 2? and serving to keep the heating or cooling medium from entering the pipe 2*" and filling it. 2 indicates a device secured in any'well known manner to and extending from each plug 2". The outer end of each device engages the front wall of the adjacent manifold and serves to space the end of the adjacent pipe 2' therefrom, and in cooperation with the spacer 2 at the opposite end of the adjacent pipe 2* to prevent movement endwise or longitudinally of the adjacent pipe 2 The inner ends of the spacers 2 are preferably connected by screw threads with theplugs 2 whereby they can be adjusted to properly position the pipes 2 By making the pipes 2 of proper length and providing the spacing devices 2 the pipes are prevented from extending into the'manifolds and obstructing the flow 'of the medium therethrough. The manifolds 2 2 are preferably provided with openings which permit access thereinto, to the pipes 2 to the interior of the pipes 2,'and to the spacers 2 The openings are preferably closed by suitable caps 2*, which may have screw threaded engagement with the walls of the openings. By the form of construction, above described, it will be seen that a relatively small quantity of fluid is required to fill the circulating space throughout the entire system. It will be readily understood that under such circumstances the apparatus can be run economically with eflicient results. 2 2*, indicate the inlet and outlet connections for the heating or cooling medium connected, respectively, tothe lower and upper ends of one of the manifolds of each unit, such as the manifold 2 2* indicates a projection, such as a pipe, extending from the upper end of each manifold 2 substantially in line with the adjacent outlet connection 2 The projection 2 and adjacent outlet 2 fit into sockets formed in the adjacent braces 1 and thereby serve to connect the adjacent section or unit 2 to the supporting members 1. The

sections or units may be connected to the members 1 in any desired manner.

3 indicates a holder for the liquid. The holder 3 is arranged above and extends longitudinally substantially from end to end of the medium circulating means 2. The holder 3 is provided with one or more series of openings 3 through which the liquid flows onto the pipes 2 of the medium circulating means 2. The holder 3 may be supported in position by any suitable means, that shown vfor illustrative purposes comprising a pair of yokes 3*, each having a seat 3 resting on the upper end of the adjacent manifold 2* or 2, a rectangular frame 3 connected in any desired manner to the opposite ends of the yokes 3; and a plate 3, having depending flanges 3 which fit over the rectangular frame 3.

The plate 3 is formed with an opening 3 to receive the holder 3. The walls of the opening 3* engage with flanges or turned over edges 3 of the holder 3 to removably support the latter in operative position. 3'? indicates a cover for the holder 3.

4 indicates a flow wall or liquid guide for the liquid flowing through the opening or openings 3 in the holder '3. The purpose of this wall or guide is to control the stream or streams of liquid flowing from the opening or openings 3' and direct it or them downwardly to and against the uppermost pipe 2*. In apparatus of this character considerable difiiculty has heretofore been experienced in boring or forming the hole or holes through the holder so that the stream or streams would flow in a.downward direction onto the circulating pipes.

In forming the holes, the forming tool uswaste of material and unsanitary conditions.

My flow wall or guide causes the stream or streams to flow directly downwardly onto the pipes and thus entirely overcome these objections. This result. is accomplished by extending the wall downwardly from the discharge port or. end of the opening 3 preferably parallel to the axis thereof and .disposing it in alinement with or a plane which is tangential to one wall of the opening 3. Where, as in the apparatus herein disclosed, a plurality of discharge openings 3 are arranged in a row, a continuous flow wall 4 may be provided for the sake of simplicity and ease of manufacture. Where two rows of openings 3 are provided, as shown in the drawings, they are preferably disposed equal distances to either side of a line passing through the axes of.

the? pipes2 and a bar .4 having a width equal to the distance between the inner side walls of the openings 3 is arranged between them so that the opposite side walls of the bar will serve to guide the streams of liquid from both rows of openings downwardly.

When two rows of openings are provided, the openings 3 in one row may be staggered relative to the openings 3 in the other row to insure substantially uniform distribution of the liquid over the medium circulating means 2.

In the preferred form of construction, I form the flow wall or walls 4 integral with the walls through which the discharge open.-

ings extend to insurethe disposition of each wall 4 in a plane tangentially to the side walls of the adjacent openings 3. For this purpose, I provide on the bottom of the holder 3 a T-bar 4P in the arms of which are formed discharge openings 3 registering with the openings 3 in the holder 3. As shown, the leg of the T is of a width equal to the distance between the inner side walls of the openings 3 so that the opposite side faces of the leg will be disposed I I in a plane which extends tangential to the inner walls of the openings 3.

The liquid to be treated is delivered to the holder 3; in any suitable manner, From the holder 3, the liquid .flows bygravity over the pipes 2 successively from the upper to the lower one, from which it drops into a receiver 5. The receiver is provided with a suitable discharge pipe 5 to convey away the liquid. The receiver 5 is prefer ably supported at its opposite ends by arms 5- extending inwardly from the braces 1.

6 indicate's'a sectional casing of any. desired form for inclosing the apparatus. The

casing 6 preferably. comprises a' skeleton frame work 6' and a plurality of swingable.

sections 6 which are pivoted and detachably secured to the frame work of the-casing in The upper and any'well known manner. lower ends of the casing 6 are preferably constructed and arranged to cooperate with the flanges-3 andfthe side wallsofthe receiver 5 to entirely inclose thepipes 2. The 'swingable sections are preferably held in .position by pivoted latches 6".

As one application of my invention 1 have shown it correlated with a circulating means or system through which either a heating medium .or-a cooling medium may be caused to fiowto heat or cool milk. The milk is conveyed by suitable piping or other means to the. holder 3 from which-it flows through the openings 3', 3 downwardly onto the uppermost-pipe 2, the flow walls 4c causing the streams emerging fromthe lower ends 'of the openings 3 tofiow' straight or downwardly independently into engagement with the adjacent pipe 2 from which it flows to each of the other pipes 2 pipes.

By causing a quantityofmilk'to pass over the pipes'and causing a heating medium to pass therethrough, the apparatus may first serve to .heat .orj'p'asteurize the milk to any desired temperature; then by causing the same body of milk to flow over the pipes and causing a cooling medium to flow therethrough, the milk may be cooled to any desired degree. It will thus be seen that the apparatus may be used either as a heater or cooler, or first as a heater and then as a cooler, or vice versa, as circumstances may require.

To those skilled in the art of makingapparatus of the class described, many alterations'in construction and Widely differing embodiments and applications of my invention will suggest themselves, without departing from the spirit and scope thereof.
